Actually looking at the pic again I'm almost certain its a wings west kit...esp those rear valences. Their website should have the kit; fairly pricey ($1500?) but that is the going rate for bodykits. A LOT of people have the wings west kit; you should be able to do a search and find plenty of threads about it.
